Waste Not

Forty years ago, the steel mills and factories south of Chicago were known for their sooty smokestacks, plumes of steam, and throngs of workers. Clean-air laws have since gotten rid of the smoke, and labor-productivity initiatives have eliminated most of the workers. What remains is the steam, billowing up into the sky day after day, just as it did a generation ago.
The U.S. economy wastes 55 percent of the energy it consumes, and while American companies have ruthlessly wrung out other forms of inefficiency, that figure hasn’t changed much in recent decades. The amount lost by electric utilities alone could power all of Japan.
A 2005 report by the Lawrence Berkeley National Laboratory found that U.S. industry could profitably recycle enough waste energy—including steam, furnace gases, heat, and pressure—to reduce the country’s fossil-fuel use (and greenhouse-gas emissions) by nearly a fifth. A 2007 study by the McKinsey Global Institute sounded largely the same note; it concluded that domestic industry could use 19 percent less energy than it does today—and make more money as a result.
You know, when you run your own podcast, you always hope for the big interview, the one that will make all the hard work you do worthwhile. If I was running a sportscast, it would be an interview with Wayne Gretzky. If this was a podcast covering the doings of the Royal Family, an interview with Prince Harry would not be amiss.
And speaking of ingenuity, we talk with Nancy Knowlton and David Martin, the co-founders of Smart Technologies, though you might know them better for their invention of the digital-interactive whiteboard.
